I was diagnosed as hypothyroid and have been on 0.25 mcg of levothyroxine a day for almost two years now. In June 2012 my TSH levels were 0.91 but I had a chemical pregnancy. I got pregnant through IVF/FET in November 2012 and January 2013 but again had very early miscarriages. My TSH level is currently 1.75. Do you think I need to increase my levothyroxine dosage? I have a doctors appointment next week. If the doc does not agree would it be safe for me to adjust the dosage on my own?
Also, what could be the reason for an increase in TSH levels and is there anything I can do (other than adjust medication) to bring it down?
